Definitions

  • the invention relates to a quick coupling according to the preamble of claim 1.
  • a corresponding quick coupling is known from EP 739 222 B1 according to the preamble of claim 1, in which the Bayonet projection when twisting before entering the bayonet recess arrives with its radially projecting surface via a corresponding control surface on the inside the socket is moved, the dimensions chosen here are that the friction between the end face of the bayonet projection and the control area is relatively large to apply the desired resistance.
  • the invention is based on the object, a quick coupling to create the type mentioned, in which the Securing against axial pulling out and the rotation lock done independently of each other, so that the two types of backup according to the requirements placed on them can be carried out and designed individually.
  • a conventional bayonet lock present by a bayonet projection on the connector and a corresponding bayonet recess in the socket is formed, and a security against axial pulling out forms.
  • the anti-rotation lock is provided by the separate Ratchet reached in a corresponding recess the socket snaps into place.
  • This latch can be designed in this way designed and made from appropriate materials be that they do their job of securing against rotation particularly well fulfilled and at the same time for a noticeable, possibly audible snaps into place when the locking position is reached. If the patient has the two parts, i.e.
  • Socket and plug who wants to connect the quick coupling with each other, he is the two parts into each other, twists them against each other, so that the bayonet projection moves into the bayonet recess is used to secure against pulling out in axial Direction.
  • the end of the rotation i.e. reaching the safe position against axial pulling out, is by snapping the latch into the recess displayed.
  • loosening is only possible with a corresponding one Force possible.
  • the socket with special "meat” provided, on which the latch in the locking position slides and after reaching the locking position and is securely and firmly held after snapping.
  • the invention can be designed in a particularly advantageous manner be as specified in claim 3.
  • a special insert made of harder plastic in the connector is provided, on which the resilient locking lug is also formed it can be just like the bayonet projection be made of appropriately hard material to the to perform the desired backup tasks.
  • the outer case is made of soft plastic in order for good and smooth transition into the connected hose to care.
  • the soft one Material of the bushing has certain "lubricating properties", for a smooth and smooth movement of the bayonet projection in the bayonet recess and the latch on the Sliding and stop surface in the recess in the socket to care.
  • the latch and the essential parts that support it are made of a different material than the socket and the housing of the connector.
  • the soft material ensures one gradual transition in this connection area and acts against a kink.
  • the locking parts namely The catch and bayonet projection are made of wear-resistant material.
  • the resilient property of the locking lug is due to the Material properties supported.
  • the quick coupling is particularly advantageous in this way formed as defined in claims 5 and 6. Since the Lugs in this symmetrical design on a larger one Diameter, they have to transfer the Torque a relatively large torque arm. Farther is the formation of the flat shape (claim 6) possible which enables easy handling by the patient. The Patient can do the flat plug and the flat socket well take this in the open position, i.e. 90 ° against each other twisted, put together and then to make the Twist the lock against each other until the two are flat Align components.
  • the quick coupling shown in the drawing exists from a plug 1 and a socket 3, at the ends Hose connections are provided.
  • a plug 1 and a socket 3 at the ends Hose connections are provided.
  • the connector with the patient side and the Socket connected to the pump side.
  • the plug 1 is formed in two parts, i.e. it exists from a housing 2 made of relatively soft plastic and one Insert 4 made of relatively hard plastic.
  • the socket 3 is from the soft plastic from which the housing 2 is made.
  • the insert 4 consists of a cylindrical extension 9 which is formed on a U-shaped bracket 5.6. On the approach there are two bayonet projections opposite each other 10. In the approach is a through opening for the drug to be administered is provided in the Sealing disc 15 is located. In this through opening when making the connection, the needle shown in Fig. 3 13 introduced, which is connected to the pump. A roof-shaped Projection 16 which carries the needle 13 comes here on the end face of the extension 9 in the area of the opening Investment.
  • the bracket on which the approach 9 is arranged and in the housing 2 is inserted has two legs 6 Locking lugs 8, which are roof-shaped, the First the socket is facing.
  • In the web 5 of the bracket are notches 7 are provided, the resilient movement of the Allow webs 6 with the locking lugs 8 in the axial direction.
  • the socket 3 has an opening or recess, the one has rectangular cross-section and in which the approach 9 fits and can be introduced.
  • In the outer wall of the socket there are two bayonet recesses 17, which act as windows are trained.
  • a sliding or stop surface 11 is formed on each side, the, as described later, the leadership and the Securing the assigned locking tab is used.
  • Plug and socket are put together, the needle 13 is inserted through the sealing washer 15 and in the corresponding opening or the channel penetrates into the plug.
  • the pointed projection 16 comes here on the End face of the approach 9, i.e. in the area of opening in this approach, to plant.
  • the rotation is about 90 °, i.e. actually only 80 °.
  • the bayonet protrusions 10 in the bayonet recesses designed as windows 17 moves. And until the in the direction of rotation front surface of the bayonet projections on the corresponding Edge of the window strikes. Otherwise the Rotational movement due to the rectangular cross section of the Socket opening not hindered.
  • the locking lugs 8 are larger than the bayonet protrusions 10.
  • the lever arm, the torque sets is relatively large, so that an exact and empathetic Control of locking and unlocking is possible.
  • the two-part design of the connector enables material selection of these two parts according to their intended use technical tasks.
